Water vapor absorption properties of a novel filament composed of maleic anhydride polypropylene, polypropylene and super absorbent polymer

The aim of this study is to develop a prototype filament that can absorb water vapor without creating any feeling of wetness and can be durable against the cleaning processes. A blend of polypropylene (PP) and maleic anhydride polypropylene (MAPP) is used for the outer surface; super absorbent polymer is placed into the cavity of prototype filament. The new prototype filament can absorb water (approximately 23%) without creating any feeling of wetness and dries totally in 20 minutes. Different blend ratios have been investigated for water vapor absorbency after washing treatment and it has been found that 50% MAPP-50% PP blend with high super absorbent polymer has better washing performances.
